TOOTH-BRUSH.

To all whom it may concern:

Be it known that 1, DAVID W'nrss, a citizen of theUnited States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Tooth-Brushes; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art'to which it pertains to make and use the same.

This invention relates to improvements in tooth-brushes, and pertains more especially to a tooth-brush which has two brushing sections arranged side by side at the forward end of the handle of the brush and locked against swinging laterally and outwardly into a position back to back but free when unlocked to be swung laterally and outwardly as required to permit the brush to be inclosed in a shallow pocket-case.

One object of this invention is not only to have the brush-carrying stock of each toothbrushin section carried by a shaft extending intd and longitudinally of and through and having bearing in the forward section of the handle and to have the shafts of the brushing sections spaced laterally, but to have the rear portion of the handle divided longitudinally and between the shafts into two correspondingly oppositely arranged sections which are pivotally connected to the rear end-portion of the forward handle-section and have their axes substantially parallel with the tufts of bristles of the stocks of the brushing sections so as to permit the pivoted handle-sections to be swung from each other and toward the forward handlesection preparatory to inclosing the brush in the aforesaid pocketcase.

Another object is to have each shaft locked against rocking independently of the other shaft and unlocked or released during swinging of the pivoted handle-sections from each other the required extent.

TVith these objects in view, and to the end of attaining any other advantage hereinafter appearing, this invention consists in certain features of construction, and combinations and arrangement of parts, hereinafter described, pointed out in the claims, and illustrated in the accompanying drawings.

In said drawings, Figure 1 is a face view, largely in central section, of my improved tooth-brush. Fig. 2 is a transverse section on line 22, Fig. 1, looking rearwardly. Fig. 3 is a transverse section on line 3-3, Fig. 1, looking forwardly. Fig. 4 is a section on line 4-4, Fig. 1. Fig. 5 is a transverse section on line 55, Fig. 1, looking rearwardly. Fig. 6 is a transverse section on line 6 6, Fig. 1, looking forwardly. Fig. 7 is a side view of an open pocket-case in which the forward end-section of the handle and connected brushing-sections and the pivoted handle-sections are compactly arranged. The tooth-brush is shown full-size in Figs. 1 and 7 whereas Figs. 2, 3, 4, 5 and 6 are drawn on an enlarged scale.

Referring to the said drawings, A indicates the forward section of the handle of my improved tooth-brush, the brush-proper of which comprises two brushing sections which comprise each a stock B and tufts 7) of bristles, as shown in Figs. 3 and 6. Said stocks are arranged side by side forward of and in line endwise with the handle, and said tufts project from the faces of the stocks in the same direction. The stock of each brushing section is carried by a shaft 10 to which said stock is secured in any approved manner. The shafts 10 are parallel and spaced laterally. The shaft 10 of each stock B extends into and longitudinally of said stock and from the rear end of the stock into and longitudinally of and through and has bearing in the forward handle-section A, as shown in Figs. 1, 2 and 5.

The rear portion of the handle is divided longitudinally and centrally between the two shafts 10 (see Figs. 1, 2 and 3) into two substantially correspondingly but oppositely arranged sections D which are pivotally connected to the forward handle-section A at opposite sides respectively of the handle. Preferably each handle-section D is-pivoted at its forward end to the rear end-portion of the forward handle-section A by a pin 12 which is arranged substantially parallel with the tufts b of bristles and extends through an ear 13 formed on the pivoted handle-section and into ears 14 formed on the forward handle-section.

Each pivoted handle-section D is provided opposite the other pivoted handle-section (see also Figs. 3 and 4:) with a recess d extending rearwardly from the forward eX- tremity of the respective handle-section, and said handle-sections not only abut against each other, as at 15, but each handle-section D, as shown in Fig. 4, abuts at its forward end against shoulders 16 formed on the for ward handle-section A a suitable distance? forwardly from the rear extremity of said forward handle-section by a reduction in the. i

thickness of the forward end-portion of said forward handle-section. It will be observed therefore that the forward handle-section has its rear end-portion, which extends from the shoulders 16 to the rear extremity of said handle-section, embraced by the forward end-portions of the pivoted handlesections and occupying the forward end-portions of the recesses (Z ln-said pivoted handlesections and thereby bracing said pivoted handle-sections internally. By the construction hereinbefore described it will be observed that the relative arrangement of the parts is such as to permit the pivoted handle-sections to be swung laterally outwardly and forwardly toward the forward handle-section and into a position alongside of opposite sides respectively of said forward handle-section, as shown in dotted lines, .Fig. 1, and in solid lines, Fig. 7.

i As shown in Fig. 1, one shaft B extends into and longitudinally of the recess (Z in one pivoted handle-section and the other shaft extends into and longitudinally of the recess cl in the other pivoted handle-section, and means formed partially on the shafts and partially o nthe pivoted handle-sections are employed for preventing rocking of the shafts. Preferably each shaft B (see Figs. 1 and 3) is provided at its rear end with a lateral and outward enlargement 17 snugly arranged between the side walls of the recess (Z in the pivoted handle-section into which said shaft extends, and obviously the engagement of said walls with said enlargement of said shaft prevents rocking of said shaft independently of the other shaft, but it will be observed that during the swinging of the pivoted handle-sections into the position shown in dotted lines, Fig. 1, and in solid lines, Fig. 7, the shafts are unlocked from or released by said handle-sections and rendered free to be taken hold of at their enlargements 17 and thereupon rocked as required to swing the brushing-sections from the position shown in Figs. 1, 3 and 6 into the position shown in Fig. 7 preparatory to inclos'ing the brush in the pocket-case C shown in Fig. 7. I would here remark that the stocks B are rounded or contoured, as at 8, at their backs and at their inner sides, as shown in Fig. 6, as required to render the brushing sections capable of being swung laterally and outwardly into the position shown in Fig. 7. Each shaft is preferably formed by a piece of wire bent at the rear end of the shaft as required not only to form the enlargement 17 of the shaft but to form a forwardly facing shoulder 18' abutting against the rear end face of the forward handle-section, as shown in Fig. l, and thereby preventing forwardly endwise displacement of the shaft.
